Alienware M17x R4 Notebook Review: Ivy Bridge and the GeForce GTX 680M
by Dustin Sklavos on September 21, 2012 12:01 AM ESTIntroducing the Alienware M17x R4
Alienware recently updated their Bronze Editor's Choice award-winning M17x R4 gaming notebook to include Intel's Ivy Bridge processors and optional AMD Radeon HD 7900M series graphics or NVIDIA's new top end GK104-based GeForce GTX 680M GPU. With the move we also get mSATA support inside the chassis. The big draw with our review unit is the NVIDIA GeForce GTX 680M, which promises a substantial performance improvement over last generation's top end GTX 580M/675M, the kind of generational jump we haven't seen on the mobile side in some time.
At the same time, Alienware's M17x R4 remains largely unchanged while Clevo, MSI, and ASUS have all continued to incrementally update their gaming notebook designs. I've also had the privilege of owning my own M17x R3 over the past year and have new insights to offer on what it's like to live with this chassis design after an extended period of time. Is Alienware smart not to mess with what looks like a winning formula, or is the world passing them by?

With the M17x R4 I'm going to be a little lazy and refer you back to my review of the M17x R3. Why? Simply put, I can't find any changes between the two chassis designs...at all. Internally Alienware has definitely updated the M17x, but externally this is the exact same notebook and while I was in love with this design before, time hasn't been as kind to it as I'd like.

Typically we get Ivy Bridge systems with the entry-level Intel Core i7-3610QM, but our Alienware systems tend to be a bit better equipped and that's true here. The i7-3720QM is a healthy step up from last generation's i7-2720QM, able to turbo up to an impressive 3.4GHz on all four cores or 3.8GHz on a single core. It also brings with it Intel's HD 4000 integrated graphics, and NVIDIA leverages them with their Optimus technology.
Speaking of NVIDIA technology, the big draw with the M17x R4 is the GeForce GTX 680M. Unlike last generation's GF1x4 derivative GPU, the GTX 680M is based on NVIDIA's current top end silicon. The GK104 in the GTX 680M is the same chip that powers the GTX 680, although here the 1536 CUDA cores have been cut down to 1344. That's about the only cut made, meaning this is basically the same silicon in the very impressive GTX 670, just run at substantially reduced clocks. The core clock now runs at only 719MHz with a boost clock of 758MHz, but the most painful cut is the GDDR5 clock. Where NVIDIA was able to hit a staggering 6GHz on the desktop (and their memory controller allows you to pretty much push the GDDR5 chips to their limits; my GTX 680 is at 6.7GHz on the memory), the GDDR5 on the GTX 680M is running at a paltry 3.6GHz. That means that while generationally shader and texturing power have increased tremendously, the memory bandwidth increase has been much more modest, and that's on a chip that's already throttled largely by memory bandwidth. Interestingly, the GTX 680M in the M17x R4 sports 2GB of GDDR5 while the GTX 680Ms offered by other vendors have 4GB, but this shouldn't be counted against it as even desktop GTX 680s with 4GB of GDDR5 haven't proven to need the extra video memory.
Of course, Alienware offers alternatives to the GTX 680M, which is a hefty $550 upgrade. The default GTX 660M is a glorified desktop GTX 650, built on the Kepler architecture and sporting 384 CUDA cores, a healthy 835MHz core clock, and 4GHz on the GDDR5. That chip really is a fine starting point for gamers, but leave it to AMD to offer what's probably going to wind up being the best price/performance option (just as they tended to last year), the Radeon HD 7970M. That's $200 for an upgrade to a fully enabled Pitcairn GPU that offers a notable improvement in performance over the $250 GTX 675M upgrade, which is just a rebranded GeForce GTX 580M. We have a review of the 7970M in the works right now, but there's really no reason to shell out an extra $50 for worse performance with the GTX 675M unless you absolutely have to stay in NVIDIA's ecosystem and don't want to spend up on the GTX 680M.
Outside of these components, the other gains are largely incremental. Most of the parts are actually identical to the M17x R3 (including the display), while memory speed has gotten a bump to DDR3-1600 and an mSATA port has been added along with Intel's SRT (Smart Response Technology) caching. We get a boost to Bluetooth 4.0 and the audio software/hardware has been bumped to SoundBlaster's Recon3Di. Nothing too exciting here.

General settings: use the power saver profile, minimum CPU set to 0%, maximum set to 100%, and cooling set to passive. HDD set to go to sleep after 1 minute. WiFi is set to maximum power savings. Display is set to 100 nits (not sure where that is on the W110ER -- I think it's two or three steps down from max), and the display shouldn't turn off or dim. System critical battery life should shut down at 1% (or if you can't set that low, 3%) battery life, 0% reserve battery, and no sleep warnings. Basically, we're setting things up for best-case battery life.Idle testing: run laptop until it's out of power (<3% battery). Audio should be muted, WIFi disabled, and that's it. I use a batch file to spit out the time every minute to a text file, and then you just subtract the start time from the finish time to get battery life. (Note that this is not truly idle, as the Batch file needs to access storage every minute.)
Internet testing: we open saved versions of four web pages every 60 seconds in Internet Explorer. Again I use a batch file to do this, that also spits out the time every minute. IE is set to empty temp files on exit. The batch file closes IE and restarts it, with the home pages set to these four: http://images.anandtech.com/reviews/mobile/interne...
Sounds like Monster does have better battery life than stock W110ER, though, given you're able to watch four hours of movies.

I am not able to test internet at this time.I'm able to set most of those settings to spec. Wifi adapter is disabled and wifi turned off. I've set display at 40% brightness on battery life.
It is setup for 1% battery life shutdown, sleep is disabled. Everything else set to your suggestions.
The laptop is currently running. 11 minutes have passed to reach 96%. Projected idle is around 260 minutes. Will report again once it is complete.
Drasca - Sunday, September 23, 2012 - link
I'm at the 91 minute mark and there's still 70% left.Projected idle is approx 300 min at this point.
That is in-line previous video use.
Drasca - Sunday, September 23, 2012 - link
4% at the 4 hr 25 minute (265 minute) mark.System shutoff at 4 hrs 26 minutes as I was looking up the nvidia control panel.
Upon resume, reports 1% battery.

Ok, there's a distinct possibility I have been testing in High Performance mode this entire time. If that is the case, then there's a battery floor for 266 minutes, and Vivek's numbers make more sense.Additionally, I am distinctly not able to guarantee 100 nits.
I cannot do further testing today. Either way, we have another benchmark.
JarredWalton - Sunday, September 23, 2012 - link
So you measured 266 minutes at idle? Seems rather low compared to Vivek's numbers, unless some other setting is messed up. I just wish I had done the Monster 1.0 testing so I could respond with confidence in regards to the numbers.Drasca - Monday, September 24, 2012 - link
Yes, I was able to reach 266 minutes minimum.My setup is not a perfectly clean Win 7 build. I discovered I still had lavasoft ad aware, and some other processes in the backround (using minimal CPU, not doing active scans). I also suspect I have been doing high performance mode, requiring minimum 100% CPU as opposed to 0-5% and the brightness seemed higher than 100 nits even at 40%. That last bit is a subjective look, as I do not have light measuring equipment on hand.
I have the AUO matte display, which likely has different brightness characteristics than the one you and Vivek received.
So there's multiple variables. Mine look like there's been CPU usage, as its about what I expect from watching videos.
Still, Vivek's numbers are pretty amazing.

Coasting by on the same chassis is not good. Happens across this company's entire lineup; my M18x R2 shares the same glaring design flaw (melting SLI cable hehe) as the R1, something they should have taken the time to fix. Good thing there's a workaround for people willing to pop the lid on the machine.Speaking of price, if you're in the military you might be surprised at what you can get these machines for, but take my advice, skip out on the SLI laptops. The SLI cables aren't built last.

My SLI cable never melted...shadowyani - Friday, September 21, 2012 - link
I'm envious of your AW experience :) My R1 and replacement R2 both had cables that fried on top of the heat-sinks. It was a big sigh of relief when I discovered how easy it was to fix. I'm a happy AW camper now though.
